Wargame: AirLand Battle

This looks like a great game... but I was wondering what I should and shouldn't buy. The combo of ALB and the original EE looks great, and is only $5 more than ALB by itself, but is it worth buying the combo if I'll spend all my time playing ALB anyway? Is EE worth digging into on its own? Bottom line... should I get the combo with both games, or just ALB?

EE is a bit different, but quite nice too. The single player campaign is scripted, but it has some really good missions in it. And some turkeys too. The MP games have a nice, slow, positioning matters feel compared to the much more hectic ALB games. (I have only dabbled a bit in EE multiplayer).
